Installation
Connecting a computer
1 Verify that the QC-300 and computer power are off.
2 Connect a computer COM port to the QC-300 RS-232 serial
port using a standard straight-through serial cable (Metronics part
number 11B12176). Make sure the cable connectors are tight, but
do not overtighten the connector screws.
3 Apply power to the computer, and then the QC-300. The
default QC-300 settings for communication over the
RS-232 serial port are shown here.
• Baud rate: 1200
• Parity: None
• Data bits: 7
• Stop bits: 1
• Flow control: Hardware
4 Launch the computer application that will be used to communicate with the QC-300, and configure the
communication properties of the computer’s COM port and QC-300 to match.
Connecting optional CNC outputs
The optional CNC joystick and amplifier outputs are connected
at the CNC output connector on the rear of the QC-300.
1 Verify that the QC-300 and CNC amplifier are off. Connect
the CNC amplifier and joystick to the 26-pin D-sub connector
on the rear of the QC-300.
2 Make sure the connector is fully inserted and
make sure the cable connectors are tight, but do
not overtighten the connector screws.
